CAN

SPECIFICATION forming part of Letters Patent No. 419,647, dated January21, 1890. Application filed May 24:, 1889. $erial No. 311,955. (Nomodel.)

To all whom it may concern:

Be it known that I, DANIEL B. DENISON, of the city, county, and State ofNew York, have invented a new and useful Improvement in Cans, of whichthe following is a full, true, and exact description, reference beinghad to the accompanying drawing.

My invention relates to that class of cans usually made of tin for thereception and preservation of articles, such as condensed milk or otherliquids or solids.

The invention has for its object the making of a cover for such can,which will be practically air and liquid tight without the necessity ofthe employment of solder. It is especially and immediately applicable inpractice for the reception and transportation of condensed milk, asabove described.

The bottom and sides of the can may be made in any suitable way. The topof the can formed for the reception of the cover is is by preference,made slightly inclined, as

the side of the lip D is made to have a slight inward projection. Thesedeviations from the vertical and horizontal have been slightlyexaggerated in the drawing, so as to render them more clear. The cover Fis provided with an upper lip at G, fitting upon the top of the can, asindicated, a downwardly-inclined portion H, fitting accurately againstthe part D, and an inwardly-projecting portion K, fitting against thepart E, While the center of the cover is made dish-shaped, as at L, forthe purpose of giving increased strength and resiliency at that portion.This cover is likewise by preference made in a die, so as exactly to fitthe innardly-projecu ing lip at the top of the can. When the dies areaccurately made, it is found that the cover will fit so accuratelyagainst the surrounding rim as to be practically air-tight, while it maybe opened by a knife or other sharp edge interposed between theoutwardlyprojecting lip of the cover and the top of the can. By makingthe parts D and H somewhat inclined from the perpendicular, asindicated, the cover has a wedge action when forced in position, therebyinsuring a tight fit. By making the part E somewhat inclined from thehorizontal the tendency of the liquid to lodge in that part is avoided,since it tends to drain toward the center of the can. The necessaryresiliency or springiness to cause a tight fit of the exterior parts issecured by the dishing shown at L, the said dishing being so arranged,as shown, as to press downward and laterally, so as to cause a tight fitbot-h beneath and at the sides of the cover.

It is obvious that the parts of the can itself, as usually made, will befastened together by solder; but the can may be arranged in any ordinaryor usual manner.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is

1. The combination of a can-cover lip consisting of a surface projectinginto the can at a slight angle from the side of the can, an inner lipprojecting farther toward the center of the can at an inclination fromthe horizontal, and a lid or cover having a side and lower surfacefitting the two angular parts of the lip of the can, the whole formingatight joint without solder, thereby permitting of the removal andreplacement of the cover, substantially as described.

2. The combination of the can-lip shown, having the exterior lip or bentportion B, projcting around the outside of the can, the inclined portionD, projecting downward and towardthe center of the can, and the inclinedportion E, projecting toward the center of the can and downward, saidportions formed of one piece of metal, each lying at an angle to theadjacent part, the coverF fitting the same and having the angularsurfaces G, H, and K, and the dish-shaped portion L, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

DANIEL B. DENISON. Witnesses:
